The main component of a solar water heating system is a solar collector. It contains a liquid that is heated when the sun shines on it. The two general categories of solar collectors are flat plate and evacuated tube collectors.

Solar Lease is an option of going solar for people who do not wish to purchase an own solar system. But on the long run savings are not as high as they would be with a purchased solar system. Leasing can also mean dependence on a solar company.

People have used a variety of power sources to run water pumps, such as human energy, animal power, hydro power, wind, and fuels for generators. A solar water pump can be run with solar power, one of the cleanest and most abundant energy resources.

A solar air collector may be used to harness the sun’s energy through the use of a suitable absorbing medium to heat the air. The air collector can be used for either industrial processes or space heating.
